ECORE HydroGrip Motivate Weld Rod, 328 LF Spool

One linear foot of rod per linear foot of seam, plus waste. Each spool holds 328 LF.

Rod is consumed by seam length, not by floor area, which catches people out. Work it from your seam plan: add up the total length of every joint between sheets, including any joints against a cove base or transition that will be welded. That figure in linear feet is your rod requirement before waste. Add a margin for the few inches trimmed off at the start and end of each weld run and for test welds. Because the same square footage can be laid out with very different seam counts, two rooms of identical size can need very different amounts of rod.

The one matching your floor colourway. We list every rod by its floor colour, not ECORE's rod name.

ECORE builds one rod per floor colourway, so there is a correct answer for every floor. The complication is that ECORE names the rod after the rod's own colour rather than the floor's, so the vendor paperwork for a floor colourway can list a rod under a completely different colour name. We have relabelled every rod on this page by the FLOOR colourway it belongs to and used the same swatches you saw when you chose the floor, so pick the swatch you recognise. If you no longer know which colourway you bought, the floor colour is on your original order and we can look it up for you.

No. Welding is what makes the seam watertight and it is a condition of ECORE's warranty.

A welded seam is a fused joint: the rod and both sheet edges melt together into one piece of material. Adhesive or sealant sits in the joint as a separate material with two bond lines that can fail, and it will not survive the cleaning regime these floors are specified for. ECORE requires the floor to be installed to its published instructions for the warranty to apply, and for a heat-welded line that includes correctly welded seams. Skipping the weld does not just risk water under the floor, it risks the warranty on the floor itself.

A grooving tool, a hot-air welder with a speed nozzle, and a spatula knife with a trim plate.

The groove is cut with a hand or powered grooving tool set to a consistent depth that stays within the wear layer. The weld itself needs a hot-air welder with a speed nozzle sized to the rod. Trimming needs a spatula knife and a trim plate, which holds the blade off the floor for the first pass. Set the welder from ECORE's published instructions for your floor line and prove the setting on an offcut before touching the floor, because the right temperature depends on the material, the nozzle and how fast the installer moves.

Only with hot-air welding experience. A bad weld is difficult to correct after the fact.

Welding is a learned skill with a narrow window. Too little heat and the rod sits in the groove without fusing, which looks acceptable until it lifts. Too much and the sheet scorches or distorts along the seam. Trimming has its own technique, and a weld gouged during trimming has to be routed out and rewelded. On a commercial floor where the seam is the waterproofing, this is worth handing to an installer who welds regularly. If you need one, we can help you find one.

After the adhesive has fully cured, never before. Welding into a green bond can lift the sheet edges.

The floor is laid and rolled first, and the adhesive is left to reach full cure. Only then is the seam grooved and welded. Heat applied over an uncured bond can release the adhesive right at the seam, which is the one place the floor cannot afford a loose edge. Cure time depends on the adhesive, the subfloor and the conditions in the room, so take the interval from ECORE's published installation instructions rather than from feel. Keep the room at service temperature through cure and welding.

It covers 328 linear feet of seam. Whether that finishes a room depends on the seam layout.

A spool is 328 linear feet, so the question is how many linear feet of seam your layout produces. Wide sheets run in long lengths give a room fewer, longer seams and use less rod. The same room broken into shorter runs, or laid at right angles to its long dimension, can easily double the seam length. Add up the seam plan before ordering, and if you land close to a spool boundary take the extra spool. Running out mid-weld means stopping the job until more rod arrives, and a weld restarted days later is more visible than one run straight through.

The same term as the floor it is welded into. ECORE publishes no separate weld rod term.

Once welded, the rod is part of the finished floor system, so it carries the warranty of the floor it is welded into rather than one of its own. ECORE's Warranty Guide lists no independent term for weld rod. That means the coverage you get depends on which line you are welding, and the terms differ across ECORE's range. Confirm the term for your specific floor before ordering. Note too that ECORE requires installation to its published instructions for any warranty to apply, so a poorly welded seam can affect coverage on the floor as well.
